Hacker group Lizard Squad may be at it again. After temporarily disrupting Xbox Live Friday night, the group claimed responsibility for disrupting the PlayStation Network Sunday night.



Though the PlayStation Knowledge Center shows the network’s status as being online, many are having issues logging into the network. Meanwhile, a number of frustrated users discussed the issue on social media site Twitter.







Lizard Squad first appeared in August, when the group targeted Xbox Live, Twitch and online game "World of Warcraft." Lizard Squad said it supports the Islamic State, the Middle Eastern extremist group. After disappearing for months, the group resurfaced in the past month with several DDoS attacks.
